Definition - What does Magnetic Resonance Angiogram mean?

A magnetic resonance angiogram is a diagnostic procedure used to examine a patient's blood vessels in order to detect abnormalities. This procedure uses magnetic imaging technology to produce pictures of the major blood vessels in the body. A magnetic resonance angiogram may also be called an MR angiography or an MRA scan.

SureHire explains Magnetic Resonance Angiogram

A magnetic resonance angiogram produces images of the body's circulatory system through the use of radio waves and a magnetic field. This examination is conducted using a magnetic resonance imaging (MRI) machine and creates three-dimensional images that can be viewed on a computer screen. An MRA permits the examining physician to inspect the walls of the blood vessels and evaluate blood flow. Magnetic resonance angiograms may require the use of contrast dyes but do not rely on ionized radiation (x-rays) for the production of images.
